Hi all,
I have had this Optiplex 780 for about a year and it has been working fine. I went out of town for a week and came back and it boots up perfectly fine but I can't get a keyboard, mouse or network to work. I have tried multiple usb wired and wireless keyboard and mouse as well as every other usb port front and back of the computer but still can't get it to detect. Also, when the computer is turned on, I have a x on the network icon at the bottom. The computer when turned on goes to the desktop but I can't do anything else because the keyboard and mouse do not work. There is no message that says no keyboard/mouse detected or any other message. Everything seems fine except it does not work.
I can't check if its a driver issue because I can't get into device manager. I tried installing Win 7 Pro again but can't boot from cd because keyboard does not work. Any suggestions?
